Description

Technical Field

[0001] The utility model relates to the technical field of mobile hard disks, and specifically relates to a tool-free portable mobile hard disk. Background Technique

[0002] With the development of technology, the storage capacity of mobile hard disks has been continuously increasing, from a few hundred megabytes (MB) in the early days to several terabytes (TB) or even higher now. At the same time, their volume has become smaller and smaller, and their weight has become lighter and lighter, further improving their portability.

[0003] As the volume of the hard disk decreases, it becomes more and more convenient for users to carry. To prevent the hard disk from being lost during transportation, many hard disks are tied with a hanging rope to facilitate the user to hang the hard disk together with items such as keychains. However, in existing hard disks, a circular protrusion is usually provided on the outer shell for the hanging rope to connect. Since the circular protrusion is usually small, during long-term use, the circular protrusion will gradually be worn and aged and then break, which may cause the hard disk to become detached and thus lost. At the same time, when the user needs to use the hard disk, either the hanging rope needs to be removed from the keychain, or the keychain has to be used at the same time, which is very inconvenient. For this reason, we have proposed a tool-free portable mobile hard disk to well solve the above drawbacks. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tool-free portable mobile hard disk to solve the problems raised in the above background technique.

[0005] The utility model is achieved through the following technical solutions: A tool-free portable mobile hard disk includes a bottom box and a top cover arranged on the bottom box. Opposite side surfaces of the bottom box are respectively provided with a rope-passing hole and an interface slot. The rope-passing hole is in a shape with an opening width gradually increasing from inside to outside. A winding column is fixedly arranged inside the bottom box near the rope-passing hole, and the winding column is used for sleeving a hanging rope. A circular protrusion is fixedly arranged on one side of the top cover facing the bottom box and near the winding column.

[0006] Optionally, a plug-in protrusion is fixedly arranged on one side of the top cover facing the rope-passing hole, and a plug-in slot for inserting the plug-in protrusion is arranged on the inner wall of the bottom box. A spring catch is arranged on one side of the top cover facing the bottom box and near the interface slot, and a catch slot for embedding the spring catch is arranged on the bottom box; in the closed state, the spring catch is located on the left and right sides of the interface slot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 - Figure 4 , a tool-free portable mobile hard disk, which includes a bottom box 1 and a top cover 2 arranged on the bottom box 1. A plugging protrusion 202 is fixedly arranged on one side of the top cover 2, and a plugging groove 104 for inserting the plugging protrusion 202 is opened on the inner wall of the bottom box 1. One side of the top cover 2 is plugged into the plugging groove 104 through the plugging protrusion 202; a spring catch 203 is arranged on the other side of the top cover 2, and a catch groove for embedding the spring catch 203 is opened on the corresponding side of the bottom box 1. The other side of the top cover 2 is embedded and connected in the catch groove through the spring catch 203.

[0021] The following describes the installation method of the bottom box 1 and the top cover 2: When the plugging protrusion 202 on the top cover 2 is inserted into the plugging groove 104, as the other side of the top cover 2 gradually tilts into the bottom box 1, the spring catch 203 on the top cover 2 will touch the inner wall of the bottom box 1 and thus be squeezed. When the spring catch 203 moves to the position of the catch groove, the spring catch 203 will pop out into the catch groove, thereby completing the fixation of the bottom box 1 and the top cover 2, and further realizing a tool-free installation method.

[0022] In order to make the disassembly and separation of the bottom box 1 and the top cover 2 more convenient, a finger buckle groove 204 is opened on the top cover 2 on the side close to the spring catch 203, so as to facilitate the user to insert the fingernail into the finger buckle groove 204, and further enable the user to easily open the top cover 2.

[0023] Furthermore, through holes 101 and interface grooves 102 are respectively opened on the opposite two side surfaces of the bottom box 1. The through hole 101 is used for a hanging rope to pass through, and the interface groove 102 is used to connect to an external port. The through hole 101 is in a shape with an opening width gradually increasing from the inside to the outside, so that the hanging rope inside the bottom box 1 can be more concentrated, thereby making the connection of the hanging rope more firm. A winding column 105 is fixedly arranged at a position in the bottom box 1 close to the through hole 101. The winding column 105 is used for the hanging rope to be sleeved. When installing the hanging rope, the user can pass the hanging rope through the through hole 101 and sleeve it on the winding column 105 inside the bottom box 1, and then cover the top cover 2 on the bottom box 1 according to the installation steps to close the bottom box 1 and the top cover 2, so that the hanging rope can be fixedly connected in the inner cavity of the bottom box 1.

[0024] In order to make the components in the bottom box 1 more complete, the present application has a circuit board 3 fixedly arranged in the bottom box 1, and the USB interface on the circuit board 3 is directly opposite to the interface slot 102, so that the USB interface can be connected to an external port, thereby realizing data transmission. A plug-in socket 301 is fixedly arranged on the circuit board 3, and a plug-in circuit board 4 is also arranged in the bottom box 1, and one side of the plug-in circuit board 4 is movably plugged into the plug-in socket 301; an arc plate 103 is fixedly arranged on the winding post 105, and the side of the plug-in circuit board 4 close to the winding post 105 abuts against the arc plate 103, so that the space utilization in the bottom box 1 is more reasonable.

[0025] Specifically, a circular protrusion 201 is fixedly provided on one side of the top cover 2 facing the bottom box 1 and close to the winding post 105. When the bottom box 1 and the top cover 2 are in a closed state, the circular protrusion 201 abuts against the upper surface of the plug-in circuit board 4, and the hanging rope is fixed on the winding post 105, so that when the box body is closed, the plug-in circuit board 4 can be in a horizontal direction and the hanging rope can be fixed inside the bottom box 1; at the same time, the winding post 105 supports the plug-in circuit board 4 to avoid wear on the plugged-in side and extend its service life.

[0026] The working principle and usage process of the utility model are as follows: first, when installing the hard disk, it is necessary to insert the plug-in protrusion 202 on the top cover 2 into the plug-in slot 104 on the bottom box 1, and then gradually tilt one side of the spring ball 203 toward the bottom box 1. When the spring ball 203 moves to the ball slot on the inner wall of the bottom box 1, the closed installation of the bottom box 1 and the top cover 2 is completed.

[0027] When it is necessary to connect the lanyard to the hard disk, first use your fingers to pry open the top cover 2 through the finger buckle groove 204, then pass the lanyard through the rope threading hole 101, so that the lanyard is set on the winding post 105, and then close the top cover 2 according to the above-mentioned closing and installation steps of the bottom box 1 and the top cover 2. At this time, the circular protrusion 201 on the top cover 2 will be pressed on the plug-in circuit board 4 and the curved plate 103, thereby keeping the plug-in circuit board 4 horizontal, and fixing the lanyard on the winding post 105. Compared with the traditional connection method, the lanyard of the present application is connected inside the box body, and the winding post 105 will not easily break, which slows down aging and prolongs the service life. At the same time, when the hard disk needs to be used, the top cover 2 can be directly opened, and then the lanyard can be removed, and then the top cover 2 can be covered for use. There is no need to remove the lanyard from the keychain, and the operation is simple and convenient.
